Third Thursday of the month
This open mic event is followed by a songwriter showcase at The Big Easy, a hidden speakeasy jazz club tucked down a back alley in Petaluma. It's sponsored by The Secret Song Club and has a high calibre of Bay Area talent. Each showcase features three acts, who play for 30-40 minutes each. Free entry, no cover.
The Secret Song Club is an organization run by Inside Lands creator, Drew Pearce, that sponsors songwriter events around the San Francisco Bay Area.
